Foods That Naturally Support Collagen Without Supplements
23. Spirulina: The Algae Amino Acid Stack

Spirulina, a blue-green algae, is a complete protein, meaning it contains all the essential amino acids needed for collagen production. It's particularly rich in glycine and proline, the main amino acids that make up the collagen molecule. Spirulina is also a powerful antioxidant, protecting existing collagen from damage, and it has anti-inflammatory properties that support overall health. Whether added to a smoothie, a protein shake, or mixed into a dip, spirulina provides a concentrated, plant-based source of the building blocks your body needs.
24. Black Beans: The Amino Acid and Zinc Provider

While our list covers a variety of legumes, black beans are a standout for their role in collagen production. They are a fantastic source of plant-based protein, providing the amino acid building blocks like proline and glycine needed to form collagen. Additionally, black beans are rich in zinc, a critical mineral that acts as a cofactor for the enzymes responsible for synthesizing collagen. By incorporating black beans into your diet—whether in soups, salads, or as a side dish—you're providing your body with both the necessary building blocks and the key mineral cofactors to maintain healthy collagen levels.
